Chapter 901

"Lao Huang, can you speak? If you can't speak, hold it. No one treats you as a mute!"

As soon as Huang Feng's voice fell, Fang Yong, the leader of Northwest Airlines, was not happy. Before Zhuang Jianye opened his mouth, he took Huang Feng back and said with a straight face: "how can Lao Zhuang be a loser? It's just that nm has gone to grandma's house. "

"Poof ~ ~"

as soon as he took a sip of tea water, Huang Feng directly sprayed it, and immediately burst out laughing: "yes, yes, Lao Fang's summary is in place, the summary is in place!"

Zhuang Jianye can see that these two are not good birds. They are more and more poisonous than each other. If we change them, we can't help them.

One is the leader of the successful group, holding the high-quality production project of project 10 in his hand; the other is the leader of Northwest Airlines, the cradle of domestic transport aircraft and bombers.

It can be said that stamping one's feet can make the domestic aviation industry tremble three times.

But the problem is that Zhuang Jianye is not an ordinary person, so he coughed softly: "ЗЗХХХХ - 24 vacuum electron beam welding machine, ЗЗХХ - 4500 large heat treatment furnace, ЗХХ - 60 large X-ray irradiator, 55000 ton die forging hydraulic press, 45000 ton hot die forging press and 18000 ton multi-directional die forging hydraulic press, I don't think it's necessary to divide them equally, anyway, we have to share them Tengfei group is short of these things, just to stay, the fcnb-2000 good rectification, save the industry always said I Zhuang Jianye boast

"Don't Don't No After listening to Zhuang Jianye's words, Fang Yong and the cat who stepped on the tail quickly stopped: "these things are all big guys. Do you have a place for Tengfei group? Let's share it for you. "

"Yes, yes, yes..." Huang Feng immediately agreed: "Lao Zhuang, I'm not talking about you. Don't always carry out fcnb-2000. Others don't know. Lao Fang and I don't know? That's a deceitful child care and fishing bait. As a result, you are still serious. "

"That is, that is Even if you fool laomaozi and Laomei, you still come to deceive us, Laozhuang This evening, Erguotou, Fenjiu, Xifeng, Wuliangye and Maotai will be the same. Otherwise, this pass will not pass! " Fang Yong quickly mended the knife.

Zhuang Jianye is also quite helpless to see two of the best tycoons in the domestic aviation industry playing the same rascal as a street thug. Even if he is shameless, he meets two more shameless. That's all. The problem is that these two shameless people are absolutely right.

In fact, let alone the fcnb-2000 project, the wd-60ml-22 turbofan engine mounted on the engine test bench is a cover up.

Because Tengfei group has only mastered a part of the preparation technology of high strength and high toughness composite materials at best, and in this science and technology tree, epoxy resin and other chemical agents with different proportions will form materials with different properties. Because of this, it can be flexibly configured in different fields according to the properties of different composite materials.

This can not only optimize the performance of aerospace, but also control the cost.

Take the F-22 fighter of the United States as an example. According to the public information, nearly 25% of the composite materials are used on the fuselage, and most of them are special composite materials with high strength and high toughness.

In fact, this kind of high strength has high toughness, but because of the different position of F-22 fuselage, there are very obvious differences in the state characteristics.

For example, im75250-4 prepreg is used for the skin and side strip of F-22 front fuselage; im7apc-2 prepreg is used for electronic equipment door; im7pr500ptm prepreg is used for internal frame and fuel tank frame; im7977-3 prepreg is used for air inlet.

A front fuselage alone uses four different composite materials. Although these composite materials are reinforced with mi7 carbon fiber, the final effect of the composite materials is different due to the different proportion of epoxy resin behind.

Some places only need high strength and toughness, some places need radar wave penetration at the same time, some places need high heat resistance, and some places need higher index in corrosion resistance

The problem is that Tengfei group only makes h-zb800 composite material, which is equivalent to im75250-4 prepreg on F-22.

In other words, what Tengfei group has mastered at present is only the manufacturing technology of some skin and side strip materials of new generation combat aircraft. As for the composite materials of internal frame, fuel tank frame, air inlet, tail, electronic equipment cabin door and other parts, Tengfei group is still at a loss as to how to break through.

If this is not the case, the new generation of combat aircraft at this time will not be pre researched, but can be formally approved. After all, the key composite materials will be produced, combined with titanium alloy and aluminum lithium alloy, and mass production will not be able to say, but one or two prototypes will be produced soon.

There is a long way to go in many aspects for the pre research has not been formally approved.The material of the new generation of combat aircraft is the same as that of the composite fan blade of the turbofan engine. Tengfei group can do it, but what it can do can withstand the impact of a 1kg bird at a relative speed of 200km at most, no matter how big it is.

The composite blades on ge-90 can resist the impact of 6 kg birds.

I can't help it. The American composite material uses im78551-7 prepreg, which is a high-strength and ultra-high toughness composite material. Compared with h-zb800 composite material of Tengfei group, it is not a bit stronger.

Because of this, the wd-60ml-22 turbofan engine is put on the engine test bench. It's OK to put it on the plane. If there's no accident, it's a big accident. After all, there are many birds larger than 1kg, and those with a relative speed of more than 200km are pediatricians. If they really want to crash, that scene

Even the real products on the engine test bench are deceptive props, not to mention the fcnb-2000 project painted on the drawing board. To use a very impolite word to describe it, there is nothing wrong with it.

Let alone those cutting-edge aeronautical and aerodynamic technologies in fcnb-2000, Tengfei group has not completely mastered them. Even if it has mastered them, the whole project will enter the engineering implementation stage, and Tengfei group will have to stare at them with its drawings, because domestic manufacturers can't do a common pivot inside, let alone aircraft.

There is no way to process this kind of things need forging, and it can not be the usual hot forging and die forging, but a precision forging process called multi-directional die forging.

And this process is the same as other forging processes, the greater the forging equipment force, the better.

The problem is that only a few domestic manufacturers have 100 ton multi-directional die forging equipment, which can process about 50 ton aircraft pivot at most, and the performance is not stable. For a large aircraft with more than 100 tons, at least more than 5000 tons of multi-directional die forging equipment can be processed.

Such a large amount of heavy equipment is completely blank in China. Now, it's good that Zhuang Jianye fooled around for a while. He brought over a 18000 ton multi-directional forging hydraulic press originally produced by Urals heavy machinery factory, which is now used in the production of Tu-204 airliner and has processed the pivot connecting the variable swept wings of Tu-160 strategic bomber in his early years.

Let alone Huang Feng and Fang Yong, that is to say, anyone in the aviation industry will have to drool greedily.
